This past January the equation was even more unbalanced: it took only eight billionaires, marking an unmistakable march toward increased concentration of wealth. Today that number has been reduced to five billionaires. Trying to understand such growing inequality is usually the purview of economists, but Bruce Boghosian, a professor of mathematics, thinks he has found another explanation—and a warning.
Today we’re thrilled to release mathsteps — the first open-source project that teaches math step-by-step. Learn about how and why we built it, and join us in making math easy and fun to learn.
